Description_x000D_ General description_x000D_ Anti-Histone Deacetylase 1 (HDAC1) antibody, Mouse monoclonal (mouse IgG3 isotype) is derived from the HDAC1-21 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to amino acids of human and mouse histone deacetylase 1 (HDAC1)._x000D_ Histone deacetylases (HDACs) are competing enzymes, belonging to histone deacetylase family. There are two classes of HDACs with six to seven different types of HDACs proteins. HDAC1,HDAC2 and HDAC3 belong to Class I HDACs and HDAC4, HDAC6, and HDAC7 belong to Class II HDACs. Class I HDACs consists of a single deacetylase domain at the N-termini and diversified C-terminal regions, while Class II contains a deacetylase domain at C-terminal position._x000D_ Application_x000D_ Anti-Histone Deacetylase 1 (HDAC1) antibody, Mouse monoclonal has been used in:_x000D_ • enzyme-linked immunosorbent assay (ELISA)_x000D_ • immunoprecipitation_x000D_ • immunoblotting_x000D_ Physical form_x000D_ solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ HDAC1 is widely studied and is shown to actively modulate the eukaryotic chromatin structure. It deacetylyses lysine residues on core histones (H2A, H2B, H3 and H4) at the N-terminal. It is a vital component of cofactor complexes and is involved in transcription regulation. Histone deacetylation results in transcription repression leading to the formation of tight nucleosomal structure which prevents DNA accessing.
